Segment Reporting [Abstract]

Business Segments

18.    Business Segments

We have two reportable segments, packaging and test. Packaging and test are integral steps in the process of manufacturing semiconductor devices, and our customers may engage with us for both packaging and test services, or for packaging or test services individually. We have concluded that our packaging and test services constitute a group of similar services within each reportable segment.

The accounting policies for segment reporting are the same as those for our Consolidated Financial Statements as a whole. We evaluate our operating segments based on gross profit and gross property, plant and equipment. We do not specifically identify and allocate total assets by operating segment. Summarized financial information concerning reportable segments is shown in the following table. The “other” column includes corporate adjustments, gross property, plant and equipment of our corporate and sales offices and capital additions that do not directly support manufacturing operations, such as research and development and infrastructure projects.
